摘要：In this article, we deal with the equilibrium selection problem, which amounts to steering a population of individuals engaged in strategic game-theoretic interactions to a desired collective behavior. In the literature, this problem has been typically tackled by means of open-loop strategies, whose applicability is limited by the need of accurate a priori information on the game and a lack of robustness to uncertainty and noise. Here, we overcome these limitations by adopting a closed-loop ap...

摘要：In this article, an optimal transportation particle method has been proposed to deal with the data fusion problem. The proposed method can handle prediction, filtering, and smoothing problems uniformly more robustly and stably than traditional algorithms. Our main idea is to approximate the trajectory in Wasserstein space, which is the set of probability distributions equipped with the Wasserstein metric. Recent literature has demonstrated the successful application of optimal transportation f...

摘要：In this article, we address a constraint-coupled optimization problem over multiagent network systems with communication time delays and unknown disturbances. The primary objective is to minimize the sum of local cost functions while adhering to both local and global constraints, the latter encompassing subsets of all decision variables. The local costs are not required to be strictly or strongly convex, as long as they are convex. Utilizing a Lyapunov approach and linear matrix inequalities, ...

摘要：In this article, we examine the role of differential positivity in the contraction analysis of discrete-time nonlinear systems with parameters that follow stochastic processes. We investigate the concept of almost sure differential positivity, which parallels the positivity of linear systems, and utilize it to derive vector-type sufficient conditions for uniform incremental exponential stability in the first moment. Employing these conditions, we demonstrate that network stability analysis can...

摘要：This note provides corrections to the statements and proofs of Lemma 4.2 and Theorem 4.1 in (Lee et al., 2023). It also discusses how the statements of the remaining theorems should be adjusted in light of the correction made to Theorem 4.1.

摘要：The linear-quadratic regulation (LQR) problem with unknown system parameters has been widely studied, but it has remained unclear whether O-similar to(root T) regret, which is the best known dependence on time, can be achieved almost surely. In this article, we propose an adaptive LQR controller with almost surely O-similar to(root T) regret upper bound. The controller features a circuit-breaking mechanism, which falls back to a known stabilizing controller when the input signal or control gai...

摘要：When deploying autonomous systems in unknown and changing environments, it is critical that their motion planning and control algorithms are computationally efficient and can be reapplied online in real time, while providing theoretical safety guarantees in the presence of disturbances. The satisfaction of these objectives becomes more challenging when considering time-varying dynamics and disturbances, which arise in real-world contexts. We develop methods with the potential to address these ...

摘要：The security of mobile robotic networks (MRNs) has been an active research topic in recent years. This article aims to secure the ubiquitous formation control of MRNs against the replacement attack, where an external robot can replace a formation robot by compromising the communication and physically interfering with the victim simultaneously. To counter this advanced attack, the novel idea of this work is to leverage the physical proximity of the formation shape and the interaction topology a...

摘要：In this note, a detective matrix-based distributed algorithm is proposed to address a distributed minimum-time consensus prediction problem for discrete-time high-order multiagent systems (MASs). Therein, each agent predicts the consensus value merely using the minimum length of individual and/or neighboring successive position time series. Compared to most existing algorithms that could only predict constant consensus values for first-order linear MASs, the present method could predict consen...

摘要：The data-driven techniques have been developed to deal with the output regulation problem of unknown linear systems by various approaches. In this article, we first extend an existing result from single-input single-output linear systems to multi-input multi-output linear systems. Then, by separating the dynamics used in the learning phase and the control phase, we further propose an improved algorithm that significantly reduces the computational cost and weaken the solvability conditions for ...
